Note:
1. Each channel operates on an separate I/O.
2. Pre-forecast:
Displayed only on LCD (No external output is provided.)
Forecast:
Displayed on LCD and LED and output (Output for each Counter)
Machine stoppage: Displayed on LCD and LED and output
(Output when the count value of one or more of Counters 1 to 9 has reached its machine stoppage value.)
3. The pre-forecast value is set as a negative offset in respect to the forecast value.
4. The machine stoppage value is set as a positive offset in respect to the forecast value.
5. This model operates on the forecast value only.

Note:
1. Ripple content: 20% max.
2. On power application, an inrush current of approx. 1.2 A flows into the Counter.
3. This signal is output as a carry signal when the Counter is used as a totalizing counter.
4. This signal can also be used as a no-voltage input signal depending on the wiring (refer to Input Connections).
